Identifying Distributions
This web page gives you practice in identifying distributions and their parameters. It is extremely important for you to be able to do this. It shows an understanding of the distributions covered in the course.
Purpose
Welcome to the page that helps you identify distributions and parameters. Below, you will find a graphic of a distribution. Your job is to determine the following about that distribution:
- the type of distribution (discrete or continuous)
- the name of the distribution
- the number of parameters it has
- the name of those parameters
- the values of those parameters

| Distribution Type | Continuous | |
| Distribution Name | Uniform | |
| Number of Parameters | 2 | |
| Parameter Name(s) | a (minimum value) b (maximum value) | |
| Parameter Value(s) | a (minimum value) = 3 b (maximum value) = 9 |
Explanation
The sample space an interval. That means this is a continuous distribution. The sample space is bounded on both sides. That means this is a Uniform distribution. The other two continuous distributions are either bounded below (Exponential) or not bounded at all (Normal).
The Uniform distribution has two parameters: a (minimum value) and b (maximum value). Both of these are obvious from the graphic: a ≈ 3 and b ≈ 9.
